It is no fundamental limitations to launch simultaneously several computer games on multiseat system. We only recommend running 3D-games on the seats, which are connected to a separate graphics card. Not every 3D-game requires such approach, for example, the game Counter-Strike normally works on the seats that connected to a same graphics card. The program supports parallel operation of the game Counter-Strike simultaneously on multiple seats. In particular, we have successfully tested such versions as: Counter Strike 1.5, Counter Strike1.6, Counter Strike Source. For a reliable and stable work of 3D-Game it is recommended to use a graphics card based on NVidia GPU.
